TIRE-BOOT FASTENER.

Specification of Letters Patent.

Patented Oct. 26, 1920.

Application filed January 25, 1918. Serial No. 213,766.

T 0 aZZ whom it may concern:

Be it known that I, WILLIAM MARTIN Barr, a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented new and useful Improvements in Tire-Boot Fasteners, of which the following is a specification.

This invention relates to a detachable boot for use upon automobile tires in the event of a blowout or other injury to the tire and it consists in the novel features hereinafter described.

An object of the invention is to provide a boot fastening device which is of simple and durable structure and which may easily and quickly be applied to the wheel and de" tached therefrom and which when in position will effectually and securely hold the boot in positionabout the injured tire.

In the accompanying drawing:

Figure l is a fragmentary side elevation of a wheel showing the boot fastener in position thereon.

Fig. 2 is a central vertical longitudinal section through the device applied.

As illustratedin the accompanying drawing the boot 1 is cut from a strip of material which may be canvas or other similar flexible material. The fastener comprises a plate 2 which is curved longitudinally and provided at its outer side with a longltudinally disposed groove 3. The plate 2 is provided at its inner side and at a point midway between its ends with an outstanding lug 4. A hollow sleeve 5 is adapted to receive the lug 4: at its outer end and when the device is in position upon a wheel the said sleeve is approximately radially disposed with relation to the said wheel. A bolt 6 is inserted in the inner portion of the sleeve 5 and a nut 7 is threaded upon thesaid bolt and one face of the nut engages the inner end of the sleeve 5. The bolt 6 is provided at its inner end with a head 8 which is adapted to fit between the inner portions of the adjacent spokes of the Wheel in the vicinity of the hub thereof.

lVhen the device is applied-the boot 1 is wrapped around the puncture or fracture in the tire and the edge portions of the said boot are overlapped at the inner side of the folly of the wheel. The plate is then placed against the overlapping portions of the boot and the sleeve 5 with the bolt 6 inserted therein is placed over the lug 4 of the plate 2 and then the head 8 of the bolt is moved in between the inner ends of the spokes of, the Wheel. The nut 7 is then turned so that one face thereof is brought into close contact with the inner end of the sleeve 5 whereby the said sleeve is moved longitudinally with relation to the bolt and the said parts are expanded so that the head 6 is forced in contact with the spokes or hub of the wheel and the sleeve 5 is forced against the plate 2 which in turn clamps the overlapping edges of the boot against the folly of the wheel.

Thus the boot is held in position and the puncture or fracture in the tire is covered. This affords a temporary means for closing the puncture or fracture until such time when permanent repair may be made.

lVhen it is desired to remove the fastener and the boot from the wheel the operation above described is reversed.

From the foregoing description taken in conjunction with the accompanying draw ing, it will be seen that a boot fastener of simple and durable structure is provided and that the same may be easily and quickly manipulated to secure the same and the boot in position upon the wheel and the device may be readily detached from the wheel:

Having described theinvention claimed is:-

A tire boot fastener comprising a plate having a groove in its outer side and a stud on its inner side intermediate its ends, a sleeve engaged with the inner side of said plate and detachably receiving said stud, a bolt having one end portion screw'threaded and slidably, extended within said sleeve, the other end portion of said bolt being formed with a head adapted-for engaging the central portion of a wheel, and a nut threaded on said bolt and engaging the adjacent end of said sleeve.

In testimony whereof, I affix my signature.

WILLIAM MARTIN RAPP.
